3 Description
The LMH32404 is a quad-channel, single-ended-input
to differential-output transimpedance amplifier (TIA)
for light detection and ranging (LIDAR) applications
and laser distance measurement systems.
The LMH32404 has an integrated 100-mA clamp on
each channel that protects the amplifier and allows
the device to recover rapidly from an overloaded
input condition. The LMH32404 also features an
integrated ambient light cancellation (ALC) circuit on
each channel that can be used instead of AC coupling
between the photodiode and the amplifier to save
board space and system cost. The ALC loop should
be disabled when DC and low frequency content is
measured.
Each LMH32404 channel has integrated switches
on the output to disconnect the differential output
amplifier from the output pins and put the channel
in standby mode. When switching between different
channels, the transistion time is only 10 ns. The
LMH32404 can be placed in low-power mode using
the EN pin to conserve power when the amplifier is
not being used.
